[0025] The present application provides an objective lens assembly of a sighting scope.

[0026] In the embodiments of the present application, please refer to Figures 1 to 8 、 Figure 10 , the objective lens assembly of the sighting scope includes an objective lens barrel 110, a mounting bracket 120, a white light lens group 130, an infrared imaging lens group 140 and a laser ranging module 150; The mounting bracket 120 is installed in the objective lens barrel 110 around the circumference of the objective lens barrel 110; The white light lens group 130, the infrared imaging lens group 140 and the laser ranging module 150 are all installed in the mounting bracket 120. The front end of the mounting bracket 120 is provided with a first display window 121 corresponding to the white light lens group 130, a second display window 122 corresponding to the infrared imaging lens group 140 and a third display window 123 corresponding to the laser ranging module 150.

[0027] In the embodiments, the objective lens barrel 110 refers to a cylindrical structure at the front end of the sighting device for accommodating optical components, which serves as the shell and main support structure of the components. The objective lens barrel 110 can be a structure independent of the scope tube 200, or it can be a part of the front end of the scope tube 200. The mounting bracket 120 is an internal support structure inside the objective lens barrel 110, which is used to fix and position various optical and electronic components in the objective lens barrel 110, to ensure its stability and alignment in the objective lens barrel 110. The white light lens group 130 refers to an optical system for collecting images in the visible light band, which functions to provide visible light visual information. The infrared imaging lens group 140 refers to an optical system for collecting images in the infrared band, which functions to detect target thermal radiation or provide imaging information in low light environments. Specifically, the infrared imaging lens group 140 can be an active infrared imaging (such as a night vision imaging lens group), which images by enhancing weak ambient light (such as starlight, moonlight) or using active infrared fill light. The infrared imaging lens group 140 can also be a thermal imaging lens group, which forms a thermal image based on temperature difference by detecting infrared radiation (heat) emitted by an object. The laser ranging module 150 is used to emit a laser beam and receive the reflected laser, and calculates the distance of the target by measuring the round-trip time of the laser. It usually contains a laser emitter and a laser receiver, which are responsible for the emission and reception of laser, respectively.

[0028] To ensure the stability and position of the mounting bracket 120 within the objective lens barrel 110, the mounting bracket 120 is designed to be circumferentially positioned within the objective lens barrel 110. For example, the outer peripheral wall of the mounting bracket 120 can be circumferentially positioned by a tight fit with the inner peripheral wall of the objective lens barrel 110 or by providing limiting protrusions and grooves, thereby preventing the mounting bracket 120 from rotating or shifting within the objective lens barrel 110.

[0029] The white light lens assembly 130, the infrared imaging lens assembly 140, and the laser ranging module 150 are all mounted on the mounting bracket 120. For example, these modules can be fixed to the internal structure of the mounting bracket 120 by means of embedding, screws, clips, or adhesive. The mounting bracket 120 is designed with specific mounting positions to ensure that the relative positional relationship between the modules is maintained. The first display window 121, the second display window 122, and the third display window 123 refer to the light-transmitting or transmitting / receiving apertures reserved on the front surface of the mounting bracket 120 for the white light lens assembly 130, the infrared imaging lens assembly 140, and the laser ranging module 150, respectively, ensuring that the optical path or laser path of each module is unobstructed. Specifically, the first display window 121, the second display window 122, and the third display window 123 are through holes.

[0030] The objective lens assembly of this invention integrates functional components such as the white light lens group 130, the infrared imaging lens group 140, and the laser rangefinder module 150 onto a mounting bracket 120 within the objective lens barrel 110. Corresponding display windows are provided for each component, effectively solving the problems of product size redundancy, increased weight, reduced compatibility, and component fragility caused by traditional external layouts. This results in a compact and well-organized overall structure with a simple and aesthetically pleasing appearance, while eliminating the risk of damage to external components. This integrated design improves the compactness of the aiming device, facilitates the integrated assembly of the objective lens assembly, and greatly improves equipment assembly efficiency.

[0031] In one embodiment, such as Figures 1 to 5 As shown, the objective lens assembly 100 of the aiming device also includes a fill light assembly 160, which is installed in the mounting bracket 120. The front end of the mounting bracket 120 has a fourth display window 124 corresponding to the fill light assembly 160.

[0032] The light supplement assembly 160 is a light source device used to provide additional illumination. Its main function is to project light onto the target area to enhance the imaging effect of the white light lens group 130 in low light conditions. This assembly can be implemented in various forms, such as an array of one or more light-emitting diodes (LEDs), or other types of light sources to meet different light supplement needs. Its design should consider light efficiency, power consumption, and beam uniformity and coverage. The light supplement assembly 160 is integrated and fixed inside the mounting bracket 120. This installation method helps protect the light supplement assembly 160 from external environmental factors such as impact, dust, and moisture, while maintaining the overall compactness and structural stability of the objective lens assembly. The fourth display window 124 provides a channel for the light emitted by the light supplement assembly 160 to project into the external environment.

[0033] By adding the light supplement assembly 160 to the objective lens assembly 100 of the sighting device and ingeniously integrating it into the mounting bracket 120, the light emitted through the fourth display window 124 effectively solves the problem of poor white light imaging in low light environments. When there is insufficient ambient light, the light supplement assembly 160 can provide sufficient auxiliary illumination, allowing the white light lens group 130 to capture clearer and brighter target images, greatly improving the observation and recognition capabilities of the sighting device in night or dimly lit environments. By integrating the light supplement assembly 160 into the mounting bracket 120, the white light lens group 130, infrared imaging lens group 140, and laser ranging module 150 are all integrated into the objective lens barrel 110, further improving the compactness of the sighting device and eliminating the potential risks of product volume redundancy, weight increase, and component damage caused by external components.

[0034] In an embodiment, referring again to Figures 1 to 5 , the white light lens group 130 and the infrared imaging lens group 140 are arranged side by side in the first radial direction of the objective lens barrel 110, and the laser ranging module 150 and the light supplement assembly 160 are arranged on both sides of the white light lens group 130 and the infrared imaging lens group 140 along the second radial direction of the objective lens barrel 110; the first radial direction and the second radial direction are arranged at an angle.

[0035] In the embodiment, the white light lens group 130 and the infrared imaging lens group 140 are arranged side by side in the first radial direction of the objective lens barrel 110, that is, the white light lens group 130 and the infrared imaging lens group 140 are arranged adjacent to each other along a common radial direction (for example, a horizontal direction or a vertical direction) on the cross section of the objective lens barrel 110. This side-by-side arrangement can be realized by reserving two adjacent mounting positions on the mounting frame 120, so that the optical axes of the two lens groups are as close as possible, thereby efficiently integrating two different imaging functions in a limited radial space. This layout not only helps to reduce the overall width or height of the objective lens assembly, but also facilitates subsequent image fusion or switching operations. The first radial direction and the second radial direction are arranged at an angle, and the first radial direction and the second radial direction can be perpendicular to each other or be at a non-orthogonal angle.

[0036] The laser ranging module 150 and the fill light assembly 160 are arranged on both sides of the white light lens group 130 and the infrared imaging lens group 140 along the second radial direction of the objective lens barrel 110, which means that the two auxiliary function modules are located in the outer region of the imaging module and are arranged along another radial direction. For example, if the first radial direction is the vertical direction, the second radial direction can be the horizontal direction, and the laser ranging module 150 and the fill light assembly 160 can be located on the left and right of the imaging module, respectively. This arrangement allows the ranging and fill light functions to be independent of the imaging function, effectively avoiding obstruction or interference with the imaging light path.

[0037] By arranging the white light lens group 130 and the infrared imaging lens group 140 side by side in the first radial direction of the objective lens barrel 110 and arranging the laser ranging module 150 and the fill light assembly 160 in the second radial direction of the objective lens barrel 110, this layout effectively utilizes the limited space inside the objective lens barrel 110 and avoids physical interference and mutual obstruction of the optical paths between the function modules. This not only helps to realize the compact design of the objective lens assembly and reduce the overall volume, but also ensures that the white light imaging, infrared imaging, laser ranging, and fill light functions can operate independently and efficiently, improving the integration and use performance of the sighting device.

[0038] In an embodiment, as Figure 1 , Figures 4 to 9 The fill light assembly 160 includes a fill light lens 161, a lamp plate 163 assembly 162, and a sliding assembly 180; the fill light lens 161 is fixedly fitted to the fourth display window 124, the lamp plate 163 assembly 162 is arranged behind the fill light lens 161, and the lamp plate 163 assembly 162 is connected to the mounting frame 120 in a forward and backward sliding manner; the objective lens barrel 110 is provided with a forward and backward extending sliding groove 111 corresponding to the lamp plate 163 assembly 162; The sliding assembly 180 comprises a knob 181 and a connecting part 182. The knob 181 is externally shown on the objective lens barrel 110. The connecting part 182 is movably arranged in the sliding groove 111 and connected with the light plate 163 assembly 162 to drive the light plate 163 assembly 162 to move close to or away from the light compensation lens 161.

[0039] In this embodiment, the knob 181 is the part of the sliding assembly 180 externally shown on the objective lens barrel 110, which is usually designed as a structure convenient for users to grasp or push, such as a knob or a button, which provides an external operation interface to enable users to conveniently adjust the light compensation lamp assembly 160. The connecting part 182 is the part of the sliding assembly 180 connected with the light plate 163 assembly 162 and movable in the sliding groove 111, which can be a rod-shaped or pin-shaped structure, mechanically connected with the light plate 163 assembly 162 and guided by the sliding groove 111 on the objective lens barrel 110 to ensure smooth movement along the preset path (forward and backward direction). When the user adjusts through the knob 181, the connecting part 182 slides forward and backward in the sliding groove 111, thereby driving the light plate 163 assembly 162 to move forward and backward in the mounting frame 120.

[0040] By operating the knob 181 externally shown on the objective lens barrel 110, the distance between the light plate 163 assembly 162 and the light compensation lens 161 can be accurately controlled. When the light plate 163 assembly 162 is close to the light compensation lens 161, the light rays will be more concentrated through the refraction and convergence of the lens, thereby achieving the effect of spotlight, which is suitable for scenes requiring long-distance and high-brightness light compensation. Conversely, when the light plate 163 assembly 162 is away from the light compensation lens 161, the light rays will be more dispersed through the refraction and diffusion of the lens, thereby achieving the effect of diffuse light, which is suitable for scenes requiring close-range and large-area uniform light compensation. This adjustable light compensation function enables the objective lens assembly 100 of the sighting device to flexibly adapt to different lighting conditions and observation tasks, effectively solving the problem of single light compensation effect in fixed light compensation mode, and significantly improving the practicality and environmental adaptability of the sighting device. At the same time, this adjustment method is simple and convenient to operate, and the structure is reliable, further optimizing the user experience.

[0041] Further, please refer to Figures 4 to 8 , Figures 11 to 14The lamp plate 163 assembly 162 includes a lamp plate 163, a light supplement lamp support 164, an elastic member 167, an adapter cylinder 168, and an adjusting screw 169. The light supplement lamp support 164 includes an aluminum base plate 165 and an inner cylinder 166 connected to the rear side of the aluminum base plate 165. The lamp plate 163 is fixedly connected to the front end surface of the aluminum base plate 165. The adapter cylinder 168 is sleeved outside the inner cylinder 166 and is fixedly connected with the aluminum base plate 165. The adapter cylinder 168 is slidably installed on the mounting rack 120. The adjusting screw 169 penetrates the adapter cylinder 168 in the radial direction and abuts against the inner cylinder 166. The inner cylinder 166 is suspended in the adapter cylinder 168 by the elastic member 167 and the adjusting screw 169.

[0042] In this embodiment, the lamp plate 163 is the core light-emitting component of the light supplement lamp assembly 160, which is usually composed of one or more light-emitting diode (LED) arrays, and is used to provide the required light supplement light source. The lamp plate 163 is fixedly connected to the front end surface of the aluminum base plate 165 of the light supplement lamp support 164, and its light-emitting surface faces the light supplement lens 161 to achieve the light supplement function. The overall structure of the light supplement lamp support 164 provides stable mechanical support for the lamp plate 163 and serves as a carrier for the internal adjustment mechanism. The light supplement lamp support 164 includes an aluminum base plate 165 and an inner cylinder 166 connected to the rear side of the aluminum base plate 165. The aluminum base plate 165 is the front end part of the light supplement lamp support 164, and the lamp plate 163 is fixedly connected to the front end surface thereof as the light-emitting surface. The inner cylinder 166 extends from the rear side of the aluminum base plate 165 and forms a hollow structure for accommodating part of the elastic member 167 and abutting against the adjusting screw 169.

[0043] The adapter cylinder 168 is sleeved outside the inner cylinder 166 and is fixedly connected with the aluminum base plate 165, and the two can be fixed by screws, buckles, etc. The adapter cylinder 168 is the main structure for the sliding connection between the lamp plate 163 assembly 162 and the mounting rack 120, and provides an internal space for the inner cylinder 166 to be suspended therein by the elastic member 167 and the adjusting screw 169. The adapter cylinder 168 is usually a cylindrical structure, and its outer surface cooperates with the sliding rail 126 on the mounting rack 120 to realize forward and backward sliding. The elastic member 167 is used to provide elastic support and buffering. It can take various forms, such as coil springs, disc springs, elastic washers, or elastic rings, etc. These elastic members 167 are usually arranged between the inner cylinder 166 and the adapter cylinder 168, and under the action of the adjusting screw 169, they jointly suspend the inner cylinder 166 in the adapter cylinder 168. The elastic member 167 is used to absorb external vibration and impact, maintain the stability of the lamp plate 163 assembly 162, and provide a reaction force for the adjusting screw 169 to ensure the accuracy and repeatability of the adjustment. The adjusting screw 169 penetrates the adapter cylinder 168 in the radial direction and abuts against the inner cylinder 166. The adjusting screw 169 is usually a threaded structure, such as an adjusting screw, which can move radially by rotating to generate a radial thrust on the inner cylinder 166.

[0044] In practice, at least two elastic members 167 and adjusting screws 169 are provided, and the elastic members 167 and adjusting screws 169 are arranged at intervals in the circumferential direction of the inner cylinder 166 and are arranged opposite to each other in the radial direction. The inner cylinder 166 is suspended in the adapter cylinder 168 by the elastic members 167 and the adjusting screws 169. Since the inner cylinder 166 is suspended by the elastic members 167, the radial thrust provides radial support and limiting, and the radial position of the inner cylinder 166 in the adapter cylinder 168 can be changed indirectly or directly to fine-tune the position of the lamp panel 163. For example, the adjusting screw 169 can abut against the outer circumferential surface of the inner cylinder 166, and axial displacement of the inner cylinder 166 is achieved by radial movement; or the adjusting screw 169 can serve as a limiting screw, and the radial position of the inner cylinder 166 is precisely controlled by adjusting the extension length of the adjusting screw 169 under the action of the elastic member 167.

[0045] Through the above technical solutions, the present application realizes more fine and stable adjustment of the position of the lamp panel 163 of the light supplement assembly 160. The sliding fit of the adapter cylinder 168 and the mounting frame 120 realizes forward and backward movement adjustment of the lamp panel 163, and the suspension structure of the inner cylinder 166 in the adapter cylinder 168 allows precise position adjustment of the lamp panel 163 in the radial direction by the adjusting screw 169. The elastic member 167 can effectively absorb external vibration and ensure the position stability of the lamp panel 163 in the working state, avoiding fluctuations in the light supplement effect caused by impact or vibration. The introduction of the adjusting screw 169 allows the operator to make extremely meticulous adjustment of the lamp panel 163 according to actual needs, significantly improving the uniformity and adjustability of the light supplement effect and meeting the light supplement needs in different environments.

[0046] In an embodiment, as shown in Figure 5 , Figure 6 , Figure 8 shown, the mounting frame 120 is provided with a sliding rail 126 extending in the front and back directions, and the adapter cylinder 168 is slidably fitted with the sliding rail 126 in the front and back directions; the lamp panel 163 assembly 162 further comprises a heat-conducting band 170 extending in the front and back directions, and one end of the heat-conducting band 170 is fixedly connected to the mounting frame 120, and the other end is fixedly connected to the adapter cylinder 168.

[0047] In the embodiment, the slide rail 126 is a guide structure arranged on the mounting frame 120 and extending in the front-back direction to provide a precise linear motion track for the adapter cylinder 168 of the lamp panel 163 assembly 162. The slide rail 126 can take various forms, for example, it can be a groove machined on the mounting frame 120, or a protruding guide strip fixed on the mounting frame 120, or a guide rail system composed of ball bearings or sliding bearings. The heat-conducting band 170 is an elastic member in the lamp panel 163 assembly 162, which has a certain flexibility and elastic recovery capability. The heat-conducting band 170 can be fixedly connected with the mounting frame 120 and the adapter cylinder 168 by means of screws, rivets, welding, adhesion, etc. The heat-conducting band 170 can be made of spring steel, engineering plastic or composite material, and its shape can be sheet-shaped, rod-shaped or curved. The heat-conducting band 170 can effectively provide support and cushioning when the lamp panel 163 assembly 162 moves forward and backward, while not hindering its main motion direction.

[0048] By arranging the slide rail 126 extending in the front-back direction on the mounting frame 120 and making the adapter cylinder 168 slideably cooperate with the slide rail 126, a precise linear guide can be provided for the lamp panel 163 assembly 162, effectively avoiding the shaking, tilting or jamming phenomenon that may occur during the forward and backward movement of the lamp panel 163 assembly 162, thereby ensuring the stability and accuracy of the position adjustment of the light supplement assembly 160. At the same time, the heat-conducting band 170 added in the lamp panel 163 assembly 162 is fixedly connected at one end to the mounting frame 120 and at the other end to the adapter cylinder 168, which extends in the front-back direction to provide additional flexible support and cushioning for the sliding of the adapter cylinder 168, and can also play a role in heat conduction. The heat-conducting band 170 can absorb slight vibrations, reduce the fitting gap, and maintain stable contact between the adapter cylinder 168 and the slide rail 126, further improving the smoothness of the sliding adjustment and the positioning accuracy of the lamp panel 163 assembly 162. This double-protected sliding mechanism enables the light supplement assembly 160 to achieve more stable and precise forward and backward movement, thereby ensuring the accurate control of the distance between the light supplement lens 161 and the lamp panel 163 assembly 162, and further realizing the fine and reliable adjustment of the light supplement lamp intensity and the light converging effect, significantly improving the adaptability and imaging quality of the sighting device under different lighting conditions.

[0049] In an embodiment, please refer to Figure 1 , Figure 2 , Figures 5 to 8 The sighting device further comprises a red dot indicator lamp assembly 190 mounted on the mounting frame 120, and the front end face of the mounting frame 120 is provided with an emission window 125 corresponding to the red dot indicator lamp assembly 190.

[0050] In this embodiment, the red dot sight 190 is a device for providing quick aiming indication, which generally assists users in quickly locking targets by emitting a visible light beam (such as a laser or LED light source) and forming a visible aiming point (such as a red dot or crosshair) on the target. The red dot sight 190 is mounted on the mounting bracket 120, which means that the red dot sight 190 shares the same mounting base with the core optical components such as the white light lens group 130, the infrared imaging lens group 140, and the laser ranging module 150. This integrated mounting method ensures the compactness of the structure between the functional modules and facilitates accurate optical axis calibration during assembly, thereby ensuring the consistency of the aiming indication of the red dot sight 190 with the boresight of the white light or infrared viewing channel. The mounting method can be achieved through screw fixation, buckle connection, or adhesion, depending on the structural design of the mounting bracket 120 and the required mechanical stability. The emission window 125 is an optical channel provided on the front end face of the mounting bracket 120, which allows the aiming light beam emitted by the red dot sight 190 to smoothly exit the objective lens assembly.

[0051] By integrating the red dot sight 190 in the objective lens assembly 100 of the aiming device, a quick and intuitive auxiliary aiming means is provided for users. When users need to quickly capture targets, they can directly aim through the aiming point provided by the red dot sight 190 without relying on complex white light or infrared imaging systems for fine alignment, thereby significantly improving the speed of target capture and the convenience of operation. In addition, since the red dot sight 190 shares the mounting bracket 120 with the core components such as the white light lens group 130 and the infrared imaging lens group 140, the structure of the entire objective lens assembly is more compact, which is conducive to realizing miniaturization and lightweight design. At the same time, through accurate installation and calibration, the red dot sight is ensured to cooperate well with the main viewing channel, further enhancing the overall performance and user experience of the aiming device.

[0052] In an embodiment, as Figure 1 , Figure 2 , Figure 5 , Figure 9 and Figure 10 , the inner peripheral wall of the objective lens barrel 110 is provided with a mounting lug 112, the front end face of the mounting bracket 120 is provided with a mounting groove 127 for embedding the mounting lug 112, and the objective lens assembly 100 of the aiming device further includes a connecting screw 128, which passes through the mounting lug 112 via the mounting groove 127 and is fixedly connected with the mounting bracket 120.

[0053] Specifically, the mounting lugs 112 protruding from the inner circumferential wall of the objective lens barrel 110 serve to provide a fixed, connectable support point for the mounting frame 120 and ensure the axial and radial positioning of the mounting frame 120 within the objective lens barrel 110. These mounting lugs 112 can be annular protrusions integrally formed on the inner wall of the objective lens barrel 110, or a plurality of block-shaped protrusions uniformly distributed circumferentially. Their shape can be designed as rectangular, circular, or trapezoidal, etc. according to actual needs, to form a precise fit with the mounting groove 127.

[0054] The front end face of the mounting frame 120 is provided with a mounting groove 127 for embedding the mounting lugs 112, which is matched in shape and size with the mounting lugs 112 on the objective lens barrel 110. The mounting groove 127 is used to receive and limit the mounting lugs 112, thereby achieving the preliminary positioning of the mounting frame 120 with the objective lens barrel 110. The mounting groove 127 can be designed as an open slot to facilitate the insertion of the mounting frame 120. The connecting screw 128 is a mechanical element used to fixedly connect the mounting frame 120 with the mounting lugs 112 on the objective lens barrel 110. The connecting screw 128 serves to provide reliable locking force, ensuring the stable installation of the mounting frame 120 within the objective lens barrel 110 and preventing it from loosening or shifting under vibration or impact. The connecting screw 128 can be a screw that fixedly connects the mounting frame 120 with the mounting lugs 112.

[0055] By protruding the mounting lugs 112 from the inner circumferential wall of the objective lens barrel 110 and providing the mounting groove 127 on the front end face of the mounting frame 120 that is matched with the mounting lugs 112, the precise radial and axial positioning of the mounting frame 120 within the objective lens barrel 110 is achieved. The connecting screw 128 passes through the mounting lugs 112 via the mounting groove 127 and is fixedly connected with the mounting frame 120, forming a stable and reliable mechanical connection structure. This design not only ensures the stability of the mounting frame 120 within the objective lens barrel 110, effectively resisting external vibration and impact, but also prevents the relative displacement of the optical components, thereby ensuring the optical axis consistency of the white light lens group 130, infrared imaging lens group 140, and other optical components, improving the imaging quality and aiming accuracy of the sighting device. At the same time, this embedding and connecting method also makes the assembly and disassembly of the mounting frame 120 more convenient, which is beneficial to the production, maintenance, and repair of the product.

[0056] The present application also proposes a dual optical sighting telescope, please refer to Figures 15 to 17The dual optical sighting telescope comprises a mirror tube 200, an ocular assembly 300, and an objective assembly of the sighting telescope, the specific structure of the objective assembly of the sighting telescope referring to the above-mentioned embodiments, the objective barrel 110 of the objective assembly 100 of the sighting device being connected to the front end of the mirror tube 200, and the ocular assembly 300 being installed at the rear end of the mirror tube 200; since all the technical solutions of the above-mentioned embodiments are adopted in the dual optical sighting telescope, all the beneficial effects brought by the technical solutions of the above-mentioned embodiments are at least possessed.

[0057] The objective assembly is used for realizing dual optical collection and forming a real image through the white light lens group 130 and the infrared imaging lens group 140. The ocular assembly 300 is usually composed of multiple lenses, and the design needs to balance the magnification, field of view, and exit pupil distance, for magnifying the real image and optimizing the imaging quality. The objective assembly and the ocular assembly 300 realize the high-precision and high-brightness imaging function of the sighting telescope through precise optical design and parameter matching. By highly integrating the white light imaging, infrared imaging, and laser ranging functions in the objective barrel 110, the dispersed structure of the traditional external device layout is avoided. This integrated design effectively reduces the overall volume and weight of the product, improves the compactness and adaptability of the structure; at the same time, the functional modules built-in the objective barrel 110 are physically protected by the objective barrel 110 and are not easily affected by external force impact or vibration, thereby significantly reducing the risk of component damage and precision deviation, greatly improving the durability and environmental adaptability of the product, and meeting the harsh standards of military and outdoor applications.

[0058] In an embodiment, the dual optical sighting device further comprises a visible light sensor 400, an infrared imaging sensor 500, a focusing assembly 600, a control assembly 700, a position sensor 800, and a driving assembly 900; The focusing assembly 600 comprises a focusing wheel set 610 and an adjusting rod 620, the focusing wheel set 610 being rotatably connected to the mirror tube 200, the adjusting rod 620 being movably arranged in the mirror tube 200, and the focusing wheel set 610 cooperating with the adjusting rod 620 to drive the adjusting rod 620 to move forward and backward when the focusing wheel set 610 rotates; The visible light sensor 400 is fixedly connected to the front end of the adjusting rod 620 and is arranged corresponding to the white light lens group 130, and the position sensor 800 is arranged corresponding to the adjusting rod 620 to detect the moving position of the adjusting rod 620; The infrared imaging sensor 500 is arranged corresponding to the infrared imaging lens group 140 and is fixedly connected to the output end of the driving assembly 900, and the control assembly 700 is used for receiving the position signal of the position sensor 800 and controlling the driving assembly 900 to drive the infrared imaging sensor 500 to move forward and backward, so as to realize the synchronous focusing of the white light lens group 130 and the infrared imaging lens group 140.

[0059] Specifically, the visible light sensor 400 can be a CCD (Charge-Coupled Device) or CMOS (Complementary Metal-Oxide Semiconductor) image sensor for converting the visible light signal received by the white light lens group 130 into an electrical signal to form a visible light image. The infrared imaging sensor 500 can be an image intensifier sensor, a high-sensitivity CMOS or CCD image sensor, or a non-cooled infrared detector for converting the infrared radiation received by the infrared imaging lens group 140 into an electrical signal to form an infrared image. Specifically, the infrared imaging sensor 500 is a thermal imaging sensor. The focusing assembly 600 is a mechanism for adjusting the focal length of the optical system. The focusing wheel group 610, as a user operation interface, is rotatably connected to the lens tube 200 for receiving the focusing instruction of the user. The focusing wheel group 610 can be drivingly connected to the adjusting rod 620 by a cam or other transmission mechanism. The adjusting rod 620 carries the visible light sensor 400 and can move forward and backward along the optical axis of the lens tube 200. The moving track of the adjusting rod 620 can be defined by the guide rail or sliding groove 111, and the precise displacement can be achieved by rotating the focusing wheel group 610.

[0060] The control assembly 700 is an electronic control unit for receiving various sensor signals and issuing control instructions. It can be realized by a microcontroller, a digital signal processor, or an application-specific integrated circuit, and has a focusing control algorithm integrated therein. The position sensor 800 is used to detect the moving position of the adjusting rod 620 in real time. It can be an optical encoder, a magnetic encoder, a potentiometer, or a Hall sensor, which can convert the mechanical position of the adjusting rod 620 into an electrical signal. The driving assembly 900 is an actuator for moving the infrared imaging sensor 500 forward and backward according to the instruction of the control assembly 700. It can be a stepper motor, a direct current motor cooperating with a precision reducer, or a voice coil motor, which can realize precise displacement through a lead screw, a gear and a rack, or other transmission methods.

[0061] The visible light sensor 400 is fixedly connected to the front end of the adjusting rod 620 and is arranged corresponding to the white light lens group 130, so as to ensure that the visible light sensor 400 is always located at the image plane position of the white light lens group 130 and is adjusted synchronously with the movement of the adjusting rod 620 to realize the focusing of the white light channel. The position sensor 800 is arranged corresponding to the adjusting rod 620 to detect the moving position of the adjusting rod 620 and acquire the focusing position information of the white light channel in real time, thereby providing accurate reference data for the subsequent synchronous focusing of the infrared imaging sensor 500.

[0062] The infrared imaging sensor 500 is arranged corresponding to the infrared imaging lens group 140 and is fixedly connected to the output end of the driving assembly 900, so as to ensure that the infrared imaging sensor 500 is located at the image plane position of the infrared imaging lens group 140 and can be accurately moved along the optical axis direction by the driving assembly 900. The control assembly 700 is used for receiving the position signal of the position sensor 800 and controlling the driving assembly 900 to move the infrared imaging sensor 500 forward and backward, so as to realize the synchronous focusing of the white light lens group 130 and the infrared imaging lens group 140. According to the white light channel focusing position fed back by the position sensor 800, the control assembly 700 calculates the required best focal plane position of the infrared imaging lens group 140 through a preset focusing curve or algorithm, and accurately controls the driving assembly 900 to move the infrared imaging sensor 500 to the position, so as to ensure that the white light and the infrared channel always maintain synchronous clear imaging.

[0063] Through the above technical solution, the user only needs to operate the focusing wheel set 610 to focus the white light lens group 130. The visible light sensor 400 moves with the adjusting rod 620, and its position is detected in real time by the position sensor 800. According to the focusing position information of the white light channel provided by the position sensor 800, the control assembly 700 accurately calculates the required corresponding focusing position of the infrared imaging lens group 140, and instructs the driving assembly 900 to move the infrared imaging sensor 500 to the position. This linkage mechanism effectively solves the problem that the white light and the infrared channel are independently focused in the dual optical sighting telescope, and the operation is complicated and difficult to synchronize. It ensures that the white light and the infrared image can remain clear under different observation distances, and significantly improves the usability, focusing accuracy and overall observation performance of the sighting telescope. In addition, the manual focusing mode of the traditional infrared imaging module is optimized to electric focusing, and the precise control of the focusing action is realized through the electric driving mechanism, which not only improves the focusing efficiency, but also guarantees the focusing accuracy, and significantly optimizes the product use performance and operation experience.
